According to research firm IDC, vendor revenue from sales of infrastructure products (server, storage, and Ethernet switch) for cloud IT, including public and private cloud, grew by 25.7% year-over-year to $6.9 billion in the second quarter of 2015 (2Q15).
The overall share of cloud IT infrastructure sales climbed to 31.4% in 2Q15, up from 26.0% a year ago.
Revenue from infrastructure sales to private cloud grew by 19.5% to $2.8 billion, and to public cloud by 30.4% to $4.1 billion.
In comparison, revenue in the traditional (non-cloud) IT infrastructure segment decreased by -3.5% year-over-year in the second quarter, with declines in all three technology segments (servers, storage and Ethernet switch).
All three technology markets showed strong year-over-year growth in both private and public cloud segments, with Ethernet switches experiencing the highest growth in private cloud at 30.1% and servers with the highest growth in public cloud at 36.6%.
“Cloud IT deployments continue to drive overall IT infrastructure growth, as customers modernize their workload portfolios onto a broad array of hybrid deployment scenarios,” said Kuba Stolarski, research director for servers and hyperscale infrastructure at IDC.
“As cloud service providers continue to expand their datacenter footprints to meet growing cloud services demand, customers increasingly rely on a variety of as-a-service offerings and traditional hosting to help meet the performance, manageability, time to deployment, and TCO requirements of their organizations. Both private and public clouds will continue to see growing demand from customers who look to optimize their workload deployments based on their own uniquely varied requirements.”
At the regional level, vendor revenues from cloud IT infrastructure sales grew fastest in Japan at 64.8% year over year, Asia-Pacific (excluding Japan) at 49.9%, Canada at 40.0%, and USA at 23.5%.
Central and Eastern Europe declined at -18.0% year over year, as the region continues to go through political and economic turmoil, which impacts overall IT spending.
